HAROLD ID. CHURCH, 015 DETROIT, MICHIGAN, ASSIGNOR TO PACKARD MOTOR, CAR COMPANY, OF DETROIT, MICHIGAN, A. CORPORATION OF MICHIGAN.

HYDROCARBON-MOTOR.

Application filed May 11,

To all whom it may concern:

Be it known that I, HAROLD D. CHURCH, a citizen of the United States, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the following is a specification.

This invention relates to the water circ1 1 lation of hydrocarbon motors, particularly as used on motor vehicles. It has specially to do with automatically controlling the water circulation system.

One of the objects of the invention is to provide a thermostatically actuated valve to control the inlet to and by-pass around the motor radiator.

Another object of the invention is to provide a thermostat unit of novel and useful construction, and one that may bereadily inserted in a radiator to control the inlet of water thereto.

Other objects of the invention will appear from the following description taken in connection with the drawings which form a part of this specification, and in which the figure is a vertical section of a device embodying the invention.

Referring to the drawings, 10 represents the upper part of a radiator of the type generally in use on motor vehicles. There is an upper tank portion 11 in the top of which is a filler cap 12, and the lower portion 13 is preferably made of tubular form to provide greater radiating surface.

Generally, the vehicle motor is arranged in the rear of the radiator 10 and is covered by a hood or bonnet, the forward part 14 of which is shown in the drawing.

It will be understood that the motor is provided with suitable water jackets, and the water is to be cooled by the radiator 10, the waterpas'sing in at the top and out at the bottom. Usually a pump is used to circulate the water and it is obvious that if the same circulation through the radiator was provided for in cold weather as in warm weather the conditions under which the motor would operate would vary considerably with the temperature. One of the objects of the present invention, therefore, is to regulate the circulation of water through the radiator and provide for bypassing some or all of the water except when the motor is operating under normal heated. conditions.

. in use.

In the form of the invention shown in the drawings, the radiator 10 is provided with a rearward extension or tank 17 the interior of which communicates with the tank part 11 of the radiator through suitable openings 18.' A thermostat unit 19 is arranged or supported in the tank 17, and it comprises a tubular part 20 which extends through the rear wall ofthe tank 17 and forms an intake pipe for the radiator. A flange 21 of this tubular part 20 may be secured to the tank 17 in any desired manner. The forward end of this intake pipe is preferably guided by a cylindrical flange 22 secured to the rear face of a baflie plate or rear wall portion or extension 23, and suitable openings 24 are provided in the flange 22 to thereby spread the water in the tank 17 and prevent its splashing into the filler cap 12.

At the rear end of the tubular member 20 of the thermostat unit is a pipe connection 25, which is shown as separately formed, and as having suitable means for receiving the end of the tubes 15 and 16. Thispipe connection forms a communication between the interior of the tube 15 and the interior of the tubular member 20 of the thermostat unit, as well as a connecting passage between said tubular member 20 and the bypass tube 16. The first of these passgges is indicated at 26 and the second at 2 The thermostat unit above described has oppositely facin valve seats 28 and 29, and a valve 30 has aces 31 and 32 adapted to those seats respectively. This valve 30 is in the form of a cage or spider the ends of which are adapted to close the front and rear outlets respectively of the thermostat unit, at different times, and it is supported at its front end upon a boss 33 which is shown as an integral part of the front end of the tubular member 20, being connected is opened, whereby the water entering the thereto through a suitable spider 3 1, and at the rear end by a rod 35 adapted to slide in a boss 36 suitably formed in the pipe connection 25. Also, the valve 30 is connected to the stationary part;20 of the thermostat unit, and particularly to the boss 33 above referred to, through a thermostat 37, which is preferably arranged within the valve itself. This thermostat is of any well known expansible construction, preferably being filled with a liquid which will cause the thermostat to expand the required amount at the {desired temperature, and when it is in its cold or contracted state it will hold the valve 30 in the position in which it is shown in full lines in the drawing with the forward face 31 of the valve against the valve seat 28, so that the forward outlet of the pipe 20 is closed and the passage 27 or rear outlet of said pipe 20 pipe 20 through the passage 26 will by-pass around the radiator through the tube 16. Of course, this water which passes into and out of the tubular part 20'of the thermostat unit will by reason of the spider construction of the valve 30 circulate around the thermostat 37, and if the temperature of the water rises due to the heating action of the motor the thermostat will expand and carry with it the valve 30 toward the valve seat 29. As soon as the valve reaches that seat it will close the outlet passage 27 and the forward outlet of the pipe 20 will be opened, so thatthe water will pass into the tank 17 and from there'into the tank 11 and the radiator 10 and be, cooled. The valve is shown in dotted lines in this latter position. I

It will be understood that the thermostat unit 19 may have its parts suitably connected together, so that the unit as a whole may be inserted into and removed from the tank 17 as the case may arise.

For the purpose of indicating the temperature of the water in the circulation system'regardless of whether any of it is being circulated through the radiator or not, a temperature indicator or thermometer 38 is mounted on the thermostat unit, preferably in a boss 39 formed at the to of the pipe connection 25, so that the bulli 40 of the thermometer is in communication with the passage 26. This temperature indicator preferably extends upwardly through an opening 41 in the bonnet 14: so that it may be observed by the operator of the vehicle.

Butone form of the invention has been shown and described, but it will be understood that other forms may be made without departing from the spirit or scope of the invention as measured by the appended claims.
